If live steam is supplied directly to the tank heating coils, the collected drains in the "clean" section of the contaminated drain inspection tank are removed directly to the __________.
• Steam heating coils in cargo or fuel tanks and how condensate is handled • Purpose of a contaminated drain inspection tank and its "clean" vs "dirty" sections • Where relatively clean condensate is normally routed in a steam plant to conserve water and heat
• Think about what is collected in the clean section of a contaminated drain inspection tank: how dirty is it expected to be? • In a marine steam plant, which piece of equipment is designed to accept condensate and return it to the feed system while removing gases? • Which option(s) would normally be used only for truly contaminated or oily drains that cannot go back into the feed system?
• Identify which of the listed destinations is part of the normal feedwater/condensate cycle rather than just a waste or overflow tank • Check which equipment is specifically used to remove dissolved gases (like oxygen) from feedwater/condensate • Confirm that the chosen destination would be appropriate for relatively clean condensate coming from steam heating coils, not sludge or heavy contamination
